Marianna [84]

Answer:

ATP synthesis by oxidative phosphorylation will stop.

Explanation:

Cyanide inhibits cytochrome oxidase that passes electrons to the molecule oxygen. Cytochrome oxidase also pumps two protons from the matrix to the intermembrane space during electron transfer. Inhibition of cytochrome oxidase would not allow the transfer of electrons to oxygen and the whole electron transport chain would be stopped. There would not be any generation of proton concentration gradient to drive the process of ATP synthesis. Hence, ATP synthesis by oxidative phosphorylation will be stopped after cyanide poisoning in aerobic cells.

What three differences between RNA and DNA.
Solnce55 [7]

Answer:

DNA is double-stranded, while RNA is single-stranded. RNA contains ribose as a sugar, while DNA contains deoxyribose. Also, three of the nitrogenous bases are the same in the two types (adenine, cytosine, and guanine), but DNA contains thymine while RNA contains uracil.

Select all that apply. Mutations _____. are random. delete genes from the gene pool. add new genes to the gene pool. are changes
Svetllana [295]

Mutations are random and rare changes in the DNA sequence that can both add or delete genes. (therefore, all of the answers listed above apply)

In genetics, the term mutation represents any change in the DNA sequence of an organism. Mutations can be limited to a change in just a single nucleotide ( Single Nucleotide Polymorphisms) or it can include deletions, insertions or translocation of a longer DNA sequence, sometimes even whole genes. Mutations are rare and random events, but there are some places in the genome that are more prone to genetic mutations, called ''hot spots''.
